Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application design specifications before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD footprint matches the PCB layout constraints to guarantee proper mechanical fit and electrical connectivity during assembly.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required for space-constrained designs. The 2.0x1.6 mm package size is suitable for high-density board layouts. Consider the LVCMOS interface compatibility with downstream digital logic circuits. Verify that the enable pin functionality meets the power management strategy of the host system.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz frequency control products. The manufacturer has a history dating back to 1973, focusing on crystal and oscillator technologies. This series represents their standard XO offerings designed for modern electronic applications requiring precise timing signals.

Oscillators Replacement Considerations

Direct substitutes within the same series include other frequencies such as 18QHTF21-6.76438-OE or 18QHTF21-21.200-OE if frequency adjustment is permissible. Cross-brand replacements require matching the 4-SMD package, 1.8V supply, and LVCMOS output characteristics.
